This has nothing to do with the companies you mentioned, and everything to do with the emergence and acceptance of DevOps/SRE best-practices over the last decade or so, which can hardly be reduced to an occasional `apt update`. There is a saying how "The building codes are written in blood". this translates quite well to modern software development lifecycle. It takes a non-trivial amount of work to maintain an internet-facing system in a secure, fault-tolerant, and scalable fashion, especially when e-commerce comes into play. At least if it's anything more serious than a toy project page or "brochureware". And modern developers don't want to deal with this toil - it's a solved problem at this point - they want to code features and build products, and it's wonderful that platforms exist that enable them to do so without having to lose sleep over the CVE du-jour.
